Installing and Upgrading Internal Modules and FRUs
This document describes how to install and upgrade internal modules and field replaceable units (FRUs) in
the Cisco 1100 Series Integrated Services Routers (ISRs). The install and upgrade information is contained
in these sections:
Safety Warnings
Class 1 laser product. Statement 1008Warning
Warning
Only trained and qualified personnel should be allowed to install, replace, or service this equipment.
Statement 1030
Accessing Internal Modules
To access the internal modules on the router, you must first disconnect from the power source and then remove
the chassis cover. See the Replacing the Cover section for instructions on how to remove and later replace
the chassis cover on the routers.
Warning
Before opening the unit, disconnect the telephone-network cables to avoid contact with telephone-network
voltages. Statement 1041

Accessing Internal Modules
Replacing the Chassis Cover
The Cisco 1100 Series ISRs have a removable cover.
Do not run the router with the cover off. Doing so can cause the router to overheat very quickly.
Use a number-2 Phillips screwdriver to perform the following tasks.
Removing the Cover
To remove the cover, perform the following steps.

Step 5
Read the Safety Warnings and disconnect the power supply before you perform any module replacement.
Confirm the router is turned off and disconnected from the power supply or power supplies. If a redundant power is
used, disconnect from the redundant power supply.
Place the chassis on a flat surface.
Remove all the screws on the both sides of the router; seven on each side.
Pull the cover to disengage the slots along the front (bezel) edge of the chassis, as shown in the figure below.

Locate the cover hooks on the mating slots and slide the cover towards the bezel side.
Install seven screws on each side.
Locating Internal and External Slots for Modules
This section describes the locations of internal modules on the router motherboard. Internal modules include
PoE daughter card on the Cisco1100 Series ISRs.

Step 8
Read the Safety Warnings and disconnect the power supply before you perform any module installation.
Confirm the router is turned off and disconnected from the power supply.
Open the chassis according to the instructions in the Removing the Chassis section.
Locate the three metal standoff holes, and install the metal standoffs into the three holes. Make sure that the standoffs
are straight when installed. Tighten them gently but firmly, to a torque of 6-8 in-lbf.
Place the PoE daughter card on top of the three metal standoffs, lining up the screw holes in the PoE daughter card with
the metal standoffs.
Gently push the PoE daughter card down towards the system board until it is firmly fixed.
Insert the three M3 (48-0530-01) screws provided, through the PoE daughter card and into the metal standoffs. Tighten
the screws using a torque of 5 in-lb.
Close the chassis cover according to the instructions in the Replacing the Cover section, and connect the power supply
cable.

Removing and Replacing the Internal PoE Daughter Card
Use the following procedure to remove and replace the Internal PoE daughter card:
Removing and Replacing the USB Flash Token Memory Stick
Step 1
Step 2
Step 3
Step 4
Read the Safety Warnings and disconnect the power supply before you remove or replace the module.
Open the chassis, locate the PoE daughter card assembly.
Remove the three M3 (48-0530-01) screws.
Pull the PoE daughter card out of the connector. If replacing the card, insert the new PoE daughter card and tighten the
screws to a torque of 5 in-lb.
Step 5
Place the removed card in an anti-static bag to protect it from ESD damage.
Note
To upgrade the PoE daughter card, follow the steps mentioned in the Installing the Internal PoE Daughter Card
section.
Removing and Replacing the USB Flash Token Memory Stick
The Cisco 1100 Series ISRs contain port for a 1 GB flash token memory stick to store configurations or Cisco
IOS XE consolidated packages.
Only Cisco USB Flash memory modules are supported by Cisco routers.Note
Caution
Do not remove a USB Flash memory module when issuing some file access command or a read/write
operation to the Flash memory module when it is processing. The router might reload or the USB Flash
memory module can be damaged. You can check to see if the USB activity LED on the router front panel
is flashing, prior to the removal of the USB device
To remove and then replace a USB flash token memory stick from the router, follow these steps:
Step 1
Step 2
Pull the memory stick from the USB port.
To replace a Cisco USB Flash memory stick, simply insert the module into the USB port. The Flash memory module
can be inserted in only one way, and can be inserted or removed regardless of whether the router is powered up or not.
What to Do Next
This completes the USB Flash memory installation procedure.
